Batteries paired with tidal power

Batteries paired with tidal power

For the first time, energy storage batteries will be paired with tidal energy generation technology to produce ‘continuous green hydrogen’ fuel.

The first-of-its-kind project, on the island on Eday, Orkney, will help smooth the peaks and troughs of tidal energy generation which naturally result from the movement of the tides.

The batteries will be vanadium-powered, rather than lithium-powered, making them more resilient to degradation caused by continuous tidal activity.

Matt Harper, chief commercial officer at Invinity, manufacturer of the vanadium batteries, said to Current that they are “the perfect partner” for tidal power, as they can continually absorb then dispatch four or more hours of continuous power, multiple times a day for decades.

He added, “Invinity eagerly anticipates working with EMEC [the European Marine Energy Centre] to validate both their vision, and our [vanadium flow batteries] unique fit, for this revolutionary application.”
